ABSTRACT:
The drive mechanism for the oscillating tool has a transmission device comprising a band, rope or the like oscillating longitudinally under tension. This transmission device is driven by a connecting rod driven by an eccentric pin which is drivable with an electric motor. To reduce manufacturing expenses and lengthen service life as well as provide a higher operating performance, the connecting rod is pivotally connected to rocker member, with whose free end the transmission device, e.g. a band, extending transverse to it, is connected. To accomplish this the free end of the rocker member is provided with a clamping device for the transmission device and a coupling bolt on which an eye of the connecting rod is engaged.
